@Viacheslav vlans are working fine.

I just tried replacing my vyos vlan DHCP scopes with a relay and passing back to my Windows 2019 server that is already set up and working as a DHCP server for my main LAN.

I definitely am not using large port-ranges. A pretty standard setup using a zone-based firewall.

Also affected by this. Reboots take almost 10 minutes before the device is usable. Commits take a long time as well.

Well, shame on you in that case ;0)

Well, shame on me for not trying. Appreciate you checking that on my behalf.

I'm somewhat agnostic to the implementation method. Whether as raw options or explicitly supported options handled natively in the CLI. Both work for me.

I see in v1.2.3 that the option to supply client-id and hostname exists which is great. My ISP requires the sending of DHCP Option 60 (VCI) in order to correctly get a lease. In EdgeOS it ends up looking like the following

Fully supportive of this. My ISP (Swisscom) require the setting of DHCP option 60 (vendor-class-identifier) in order for an IP to be granted to xDSL lines.
